PDF Filter


If you routinely update your Mac’s operating system, you should be able to shrink your PDF without installing any new apps. This is a cool feature in OS X that many people don’t know about.

First, open your PDF in preview. Usually you can just double-click the file, but if you have a PDF reader such as Adobe Reader installed, you’ll want to right-click > Open With > Preview). Then click File >Export, and in the Quartz Filter drop-down box, select Reduce File Size.

This only works with large PDF files. Try doing this with a very small PDF (less than a few MB), and these could actually increase in size.

PDF Squeezer


Other than the simple process above, there really isn’t much choice for reputable, free PDF compression tools for Mac users. If you want to control the output quality, etc. of your compressed PDFs, your best bet is to download an app such as PDF Squeezer ($5.99).
